Best Known (51, 142, s)-Nets in Base 8

(51, 142, 98)-Net over F₈ — Constructive and digital

Digital (51, 142, 98)-net over F₈, using

t-expansion [i] based on digital (37, 142, 98)-net over F₈, using
- net from sequence [i] based on digital (37, 97)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 37 and N(F) ≥ 98, using
    - F₅ from the tower of function fields over F₈ by van der Geer and van der Vlugt [i]

(51, 142, 144)-Net over F₈ — Digital

Digital (51, 142, 144)-net over F₈, using

t-expansion [i] based on digital (45, 142, 144)-net over F₈, using
- net from sequence [i] based on digital (45, 143)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 45 and N(F) ≥ 144, using
    - Drinfeld modules of rank 1 [i]

(51, 142, 1672)-Net in Base 8 — Upper bound on s

There is no (51, 142, 1673)-net in base 8, because

1 times m-reduction [i] would yield (51, 141, 1673)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 21 705426 388382 644584 668025 224964 577715 847574 879910 478402 231489 418955 938272 246183 523543 652559 207119 357223 384646 552677 825051 089280 > 8¹⁴¹ [i]
